To support a nullable type you just have to add a @Nullable annotation on your @Provides method that returns the nullable type and Dagger will accept it.

If you don't, Dagger will complain that you can only provide nullable types from @Nullable annotated methods.

if you don't want to go down the road of having nullable objects injected, you can return an Optional<Navigator> in your dagger module - you'll end up with cleaner code in the long run.
